I’m in Canada, and using Shopify Payments does not eliminate the 2.9%+$0.30 fee. This will always be charged.
If, however, you use another payment acceptor, like Paypal, then they would charge you an additional 2% on top of that, plus whatever Paypal charges. I’m not sure about Paypal because I’ve only used Shopify Payments; one set of fees is hefty enough.
